Which smartphones will have the most powerful phone battery in 2023?

Most giant phone battery makes smartphones have long-lasting life. All the phones on our top battery life list will save you from worrying about when or if you’ll be able to charge it again. Practically, it equates to using the device continuously for a whole day and beyond. Our top picks for longest-lasting smartphones span a wide variety of prices. Our most durable device is a gaming-focused $999 cellphone, and our runner-up is the most expensive iPhone you can purchase, but we also carry devices in the $199 to $300 price range. Alternative intermediate versions exist, focusing on battery life rather than cost. There is a list of the giant phone battery so get in-depth knowledge of biggest phone battery.

The Asus ROG Phone 6 Pro (15:30)

In theory, the Asus ROG Phone 6 Pro’s 6,000 mAh battery should allow it to operate for many days before recharging. This gaming phone, however, has a battery life that much outstrips our expectations, clocking in around 15.5 hours in our testing. It’s even more astonishing to consider that the ROG Phone 6 Pro can increase its refresh rate to a maximum of 167 hertz and still maintain that time.

iPhone XS Max 14 Pro (13:39)

Apple’s Pro Max iPhones have a reputation for durability, but they lasted only a short time. The iPhone 14 Pro Max’s record-breaking battery life is one more reason we recommend it as the most incredible smartphone currently available (and certainly the best iPhone you can buy). An example of a long-lasting smartphone that falls farther down the list is the iPhone 13 Pro Max, which helps put the results in context. And the iPhone 14 Pro Max, which has an always-on display that you’d think would reduce battery life, beat it by nearly one hour.

Motorola Moto G Power 2022 (13:15)

Motorola continues updating the Moto G Power, and if the improved battery life lasts for days at a time, then why not? In our battery life test, the Moto G Power (2022) performed similarly to its predecessors, lasting a long time but charging slowly. The Moto G Power 2 has a slower CPU than the Moto G Power. Therefore, we are less excited about it (2021). (That phone was formerly the best in battery life, but it has been on the market for over 18 months, so we’ve removed it from our list of the best smartphones for battery life. However, you can still find it on sale, generally at a reduced price, if you don’t mind its outdated software.)

OnePlus N300 North (13:13)

Although the OnePlus Nord N300 isn’t perfect, its battery life isn’t one among them. On our battery life test, the OnePlus 6T’s endurance was identical to that of the Asus Zenfone 9 and the Nubia RedMagic 6S Pro, at 13 hours and 13 minutes. The OnePlus Nord N300 accomplished this with a display refresh rate of 90Hz, so there’s no need to worry about the phone’s battery life being negatively affected by a fast-refreshing display.

In addition, we like that this $228 phone can be charged at a rapid 33W. Unfortunately, our tests revealed that neither the cameras nor the performance of this phone was very impressive, and OnePlus only guarantees a single firmware upgrade.

Asus Zenfone 9. (13:13)

The Asus Zenfone 9 may have a small footprint, but its large battery capacity more than makes up for its diminutive size. Our battery life test lasted over 13 hours on the latest Asus flagship model with the adaptive refresh rate enabled. That alone would make the Zenfone 9 remarkable, but it did so without the assistance of a large battery.


For every smartphone we examine, most giant phone battery to live longer; it is subjected to rigorous testing in addition to real-world usage before we give it a final score. Our original Tom’s Guide Battery Life test is the gold standard for measuring mobile device longevity. We adjusted the phone’s display brightness to 150 nits to ensure reliable findings for this evaluation. We then time how long it takes for the phone to run out of battery as it uses the internet in its default browser after running a script.
